I never expected such overwhelming amount of responses! I am extremely happy you guys like them, thank you so much!

All the brass workpieces you see were actual tasks for my school, with their provided material. Unfortunately I had to hand in every single piece and I am unable to claim them even if I'm willing to pay for the cost of the material, which is literally nothing, considering it is brass and not precious metal.
Those pieces will eventually be destroyed so the material can be re-used and all the hours I spent on them were practically useless. I can remake them, of course, but it still leaves a sour taste in my mouth.

After my exams (only one week from now, yuck) I will be free from the grasp of the education system so I can finally set out to make my mark...
